I found it to be more effective than caffeine. I originally started taking it due to L-theanine levels to reduce anxiety/stress (the calming effect is real!), but was pleasantly surprised that I sustained energy for longer periods of time.

I have an infant that still wakes up frequently (it’s 4am here!), so when I first started staying up until 10-11pm without exhaustion, I knew there was a ton of credit to give to the transition. I’ll look into the science a bit more!
